* A Crown Heights man was arrested for allegedly threatening to stab a business associate and stealing $20,000 from him.

Daniels, who was busted on Tuesday, was charged with robbery, burglary, criminal trespass and weapons possession. The woman is being sought.

Coke was charged with assault, menacing and weapons possession.
